DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an I / O device in which an ID code received from a portable storage carrier is registered in a vehicle in advance.
The present invention relates to a vehicle control device that switches an operation of a main switch for forming a vehicle traveling circuit to an allowed or enabled state when the D code matches the D code.

[0002]

2. Description of the Related Art In recent years, various countermeasures have been taken to enhance security against vehicle theft. As an example of such a countermeasure, an ID code unique to a tag carried by a driver is stored, and an ID code read from the tag by using an aerial propagation signal is registered in a vehicle in advance. It is considered that the configuration is such that the operation is switched to a state in which the operation of the ignition switch, which is the main switch, is permitted only when the operation matches.

[0003]

In the above-described conventional configuration, when the engine is operated in response to the operation of the ignition switch, the driver holding the tag sets the ignition switch to the operation stop position (off position) of the engine.
If the user gets off the vehicle without operating the engine, the engine remains operated. In such an engine operating state,
Since the vehicle is in a state in which the vehicle can travel, there is a high possibility that the vehicle will be stolen. As a result, there is an unsolved problem that the original meaning of providing the tag is lost. In addition, even if the driver leaves the tag in the vehicle compartment and gets off the vehicle, there is a high possibility that the vehicle will be stolen, and some measures have been desired.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vehicle driving circuit when an ID code received from a portable storage carrier matches an ID code registered in the vehicle in advance. In a case where the operation of the main switch for forming the switch is switched to a state in which the operation of the main switch is allowed or enabled to enhance the security against theft, a situation in which the vehicle is left in a state where the vehicle can be driven due to forgetting to return the main switch. An object of the present invention is to provide a vehicular control device which can prevent the vehicle from being left in advance and can cope with a situation in which the storage carrier is left behind in the vehicle compartment, thereby ensuring sufficient safety against theft of the vehicle.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an off position for cutting off an accessory circuit and a vehicle traveling circuit, an accessory position for forming an accessory circuit, and a vehicle traveling circuit. A main switch that can be selectively operated to an on position for forming, an ID code stored therein, a portable storage carrier capable of transmitting the ID code using an airborne signal as a medium, and an ID from the storage carrier. A receiving means for receiving the code, and an operation means for maintaining the state in which the operation of the main switch is always prohibited or disabled, and
Control means for switching to a state in which the operation of the main switch is allowed or enabled when the D code is in a state in which the ID code matches an ID code registered in advance on the vehicle side. In the formed state, when the receiving continuation state of the ID code by the receiving means is stopped halfway, an auxiliary control for shutting off the vehicle driving circuit on the assumption that a predetermined circuit shutoff condition is satisfied. This is a configuration having means (claim 1).

In such a configuration, the driver of the vehicle always carries the portable storage carrier, and when the vehicle drive circuit is formed by the main switch for the vehicle travel, The receiving means receives the storage ID code of the storage carrier. At this time, when the received ID code matches an ID code registered in advance on the vehicle side, the control means allows or activates the operation of the main switch which was in the operation inhibition state or the operation invalidation state. It will switch to the state,
By operating the main switch to the ON position,
It becomes possible to form a vehicle traveling circuit.

[0007] Thereafter, when the storage medium is moved out of the receiving range of the receiving means in a state where the vehicle running circuit is formed by the main switch, the receiving state of the ID code by the receiving means is interrupted. Since the vehicle is stopped, the auxiliary control unit cuts off the vehicle traveling circuit on the premise that a predetermined circuit cutoff condition is satisfied.

Therefore, even if the driver carrying the storage carrier gets off the vehicle without performing an operation of shutting off the vehicle driving circuit by the main switch, the vehicle driving circuit is automatically shut off and the vehicle is stopped. Since it is impossible to drive the vehicle, the security against theft of the vehicle can be improved.

In this case, it is desirable that the circuit cutoff condition includes at least a stopped state of the vehicle (claim 2). According to such a configuration, the circuit for running the vehicle is not suitable for the running state of the vehicle. It is possible to surely prevent a situation in which it is easily cut off.

[0010] The auxiliary control means may be configured to output an alarm when the control for shutting off the vehicle running circuit is executed (claim 3). According to this configuration, when the driver holding the storage carrier gets off without operating the main switch to the off position, the alarm is output at the same time as the vehicle driving circuit is cut off, For example, it is possible to cope with forgetting to operate the main switch, thereby improving convenience.

[0011] The auxiliary control means may be configured to execute control for shutting off the vehicle running circuit when a predetermined delay time has elapsed from the start of outputting the alarm as described above. Item 4) With this configuration, it is possible to prevent a situation in which the automatic shutoff operation of the vehicle traveling circuit is performed more frequently than necessary.

When the delay time is set as described above, a manually operable cancel switch is provided, and the auxiliary control means is used to control the delay before the control of shutting off the vehicle driving circuit. When the cancel switch is operated during the time, the control for shutting off the vehicle driving circuit may be executed when the main switch is operated to a position other than the on position (claim 5).

[0013] According to this configuration, even after the vehicle driving circuit is once formed, even if the storage of the ID code is continuously stopped by the receiving means due to a failure of the storage medium or the like. If the cancel switch is operated within the delay time after the output of the alarm is started, the formation state of the vehicle traveling circuit can be maintained as long as the main switch is in the ON position. Therefore, even if the storage medium is broken, the vehicle can be driven to the destination. After that, when the main switch is operated to a position other than the ON position, the operation of shutting off the vehicle running circuit is performed at the time of the operation.

In addition, a human sensor is provided for detecting a state in which a person is seated in a vehicle driver's seat, and the auxiliary sensor is controlled by the human sensor when the vehicle driving circuit is shut off. The control for outputting the alarm may be performed only when the condition is satisfied (claim 6). According to this configuration, there is no possibility that a useless alarm output operation is performed in a state where no person is seated in the vehicle driver's seat, that is, in a state where the alarm itself is meaningless.

[0015] The receiving means may have a transmission function of intermittently transmitting a trigger signal using an airborne signal effective in a predetermined transmission area as a medium. An ID code transmission operation may be performed when a trigger signal is received (claim 7). According to this configuration, power consumption required for the portable storage carrier can be minimized.

The portable storage carrier is configured to transmit a lock signal and an unlock signal including the ID code, and when the lock signal or the unlock signal is received by the vehicle, the signals are transmitted to the vehicle. I included in
Door lock control means for locking or unlocking the vehicle door lock mechanism when the D code matches the ID code registered in advance may be provided (claim 8). For example, the added value of the portable storage carrier can be increased, and the cost can be reduced when the door lock mechanism is also controlled.

The auxiliary control means may be controlled by the door lock control means by the door lock control means in a state where a vehicle running circuit is formed and the reception of the ID code by the reception means is stopped halfway. The vehicle driving circuit may be cut off on the premise that a circuit cut-off condition that a lock operation is performed is satisfied (claim 9).

According to this configuration, a state in which the door lock mechanism is locked using the portable storage medium taken out of the vehicle compartment, that is, a state in which the driver gets off and the door lock mechanism is locked. When this happens, the vehicle driving circuit is reliably shut off, so that the security against theft is greatly improved.

Further, the door lock control means may determine that the ID code included in the received lock signal is the ID code received by the reception means when the control means switches the operation of the main switch to an allowed or enabled state.
If the code is different from the code, the lock operation of the door lock mechanism based on the lock signal may be canceled (claim 10).

According to this configuration, for example, when the driver
In the case where two portable storage carriers having different codes are held, the operation of the main switch is switched to a state in which the operation of the main switch is permitted or enabled in response to receiving the ID code from one storage carrier. In addition, since the lock operation of the door lock function can be performed only by the lock signal from the storage carrier, there is a possibility that the lock operation of the door lock mechanism is performed in a state where the storage carrier is left in the vehicle compartment. Can be prevented.

In this case, a manually operable cancel switch is provided, and the door lock control means is controlled by the ID code included in the received lock signal within a predetermined time after the cancel switch is operated. However, even when the control unit switches to a state where the operation of the main switch is permitted or enabled, even if the received device is different from the ID code received,
The lock operation of the door lock mechanism may be performed based on the lock signal (claim 11).

According to this configuration, even if the driver holds two portable storage carriers having different ID codes, any one of the portable storage carriers can be used within a predetermined time after operating the cancel switch. Since the lock operation of the door lock mechanism can be performed even with the storage carrier, it is practically convenient.

A configuration having a return mechanism for moving the main switch to the off position when the control of the vehicle running circuit is performed by the auxiliary control means while the main switch is at a position other than the off position; (Claim 12).

According to this configuration, when the driver holding the storage carrier gets off the vehicle without operating the main switch to the off position, the main switch is automatically moved to the off position by the return mechanism. Therefore, the convenience in the actual use condition is improved, and the useless consumption of the vehicle-mounted battery can be prevented.

Further, a return mechanism is provided for moving the main switch to the off position when the reception of the ID code by the receiving means is stopped halfway while the main switch is at the accessory position. (Claim 13).

According to this configuration, when the driver holding the storage carrier gets off the vehicle while operating the main switch to the accessory position, the main switch is automatically moved to the off position by the return mechanism. Therefore, the convenience in the actual use condition is improved, and the useless consumption of the vehicle-mounted battery can be prevented.

The parking brake switch 9 generates a brake-on signal when the parking brake is operating. The door lock detection switch 10 generates a lock detection signal when the vehicle door lock mechanism 16 is in a locked state, and generates an unlock detection signal when the door lock mechanism 16 is in the unlock signal. The door courtesy switch 11 generates a door open signal when the vehicle door is open, and generates a door close signal when the vehicle door is closed. The shift position switch 12 generates a parking signal and a neutral signal when the automatic transmission of the vehicle is in the parking position and the neutral position, respectively.

The vehicle speed sensor 13 generates a pulse-shaped vehicle speed signal having a cycle corresponding to the running speed of the vehicle while the vehicle is running. The engine speed sensor 14 generates a pulse-shaped speed signal having a cycle corresponding to the engine speed in the operating state of the vehicle engine.

The ignition switch 15 is provided on the dashboard 17 of the automobile, for example, as shown in FIG. 4, and normally, the rotation operation from the OFF position OFF which is the initial position is performed by the switch actuator 18.
(Corresponding to the return mechanism in the present invention). Also, the ignition switch 15
In the state where the operation is permitted, as shown in FIG. 5, an accessory position for forming an accessory circuit in accordance with the operation of the operation dial 15a from the above-described OFF position OFF in a general ignition switch. ACC, an ON position ON for forming an ignition circuit as a vehicle traveling circuit, and a start position ST for forming a starter circuit can be sequentially rotated to respective positions (an operating force is applied to the start position ST). During the operation to each of the above-mentioned positions, an OFF signal, an accessory signal, an ON signal, and a start signal indicating those states are generated. The switch actuator 18 has a function of moving the ignition switch 15 to the off position OFF.

The door lock mechanism 16 is configured to be operated by a door lock actuator 16a composed of, for example, an electromagnetic solenoid. The storage device 19
Is formed by storing (registering) an ID code unique to the vehicle in advance, and the control device 3 can access the storage device 19.

The engine control ECU 20 has a well-known configuration for performing fuel injection control, ignition timing control, idle control, and the like of an automobile engine. The parking signal and neutral signal from the shift position switch 12 and the vehicle speed sensor 13 are provided. In addition to the vehicle speed signal from the engine, the speed signal from the engine speed sensor 14, the ON signal and the starter signal from the ignition switch 15, a crank position signal required for engine control, an idle signal, and the like are input. I have.

On the basis of the input signals as described above, the program stored in advance, and the data stored in the storage device 19, the control unit 3 transmits and receives the transmission / reception unit 4, the door lock actuator 16a, the switch actuator 1
8. It is configured to control the engine control ECU 20.

FIGS. 2 and 3 show such a control device 3.
Of the control contents according to the present invention, a portion related to the gist of the present invention is shown, and this will be described below together with related operations. In FIG. 2, the control device 3 first starts a relatively short time timer operation of the human detection timer realized by the internal program (step S1), and thereafter waits for cyclically executing steps S2 to S4. Form a loop.

In step S2, it is determined whether or not the timer for detecting a person has timed out. In step S3, it is determined whether or not an unlock signal has been received from the ID tag 1. In step S4, the ID tag is determined. It is determined whether or not a lock signal has been received.

When the lock signal from the ID tag 1 is received ("YES" in step S4), it is determined whether the lock condition of the door lock mechanism 16 is satisfied (step S5). The lock conditions include, for example, an ID in which the door lock mechanism 16 is in the unlocked state and the ID code in the received lock signal is stored in the storage device 19.
This is established when it matches the D code.

If the lock condition is not satisfied when the lock signal is received, the process returns to the standby loop (steps S2 to S4), but if the lock condition is satisfied ("YES" in step S5). Returns to the standby loop after executing step S6 of locking the door lock mechanism 16 through the door lock actuator 16a.

When the unlock signal is received from the ID tag 1 ("YES" in step S3), it is determined whether or not the unlock condition of the door lock mechanism 16 is satisfied (step S7). This unlock condition is, for example, that the running of the automobile is stopped and the door lock mechanism 16
Is in the locked state, and is established when the ID code in the received unlock signal matches the ID code stored in the storage device 19.

If the unlock condition is not satisfied when the unlock signal is received, the process returns to the standby loop as it is (if YES in step S7), the door lock actuator After executing step S8 for unlocking the door lock mechanism 16 through 16a, the process returns to the standby loop.

When the time for the human detection timer has expired ("YES" in step S2), step S9 for restarting the human detection timer is executed, and then the driver's seat based on the output from the human sensor 7 is executed. It is determined whether there is a person who has approached within a predetermined distance from (step S1)
0). If "YES" is determined in step S10, an operation of transmitting a trigger signal from the transmission / reception unit 4 toward a predetermined transmission area is performed (step S11).

After the trigger signal transmission operation is performed, I
It is determined whether or not the answer back signal from the D tag 1 has been received for a predetermined short time t (steps S12 and S1).
3). If the answer back signal is not received within the time t, the process proceeds to step S18 shown in FIG. 3. If the answer back signal is received, the ID code in the answer back signal is stored in the storage device 19 in advance. Memorized I
It is determined whether it matches the D code (step S1).
4).

If the ID codes do not match, the process returns to the standby loop as it is. If the ID codes match, the operation is switched to a state in which the operation of the ignition switch 15 is permitted through the switch actuator 18 (step S15). After sequentially executing step S16 for giving the start permission and step S17 for setting the permission flag F to "1", the process returns to the standby loop.

As a result of the execution of steps S10 to S17 as described above, it is assumed that the driver holding the ID tag 1 storing the same ID code as that of the vehicle has approached a predetermined distance from the driver's seat. When this happens, the operation of the ignition switch 15 is switched to a state where the operation is permitted, and the engine control ECU 20 is switched to a state where the engine can be started. In this case, the permission flag F indicating that the engine can be started is set.

On the other hand, in FIG.
It is determined to be "NO" in step S10 (when a person has not approached within a predetermined distance from the driver's seat at the time when the human detection timer expires), and to "YES" in step S13. This is executed in a case (when the answerback signal is not received within a predetermined time t after the trigger signal transmission operation is performed). In this step S18, it is determined whether or not the permission flag F is set. to decide.

If the permission flag F has been set, after executing step S19 of transmitting a trigger signal from the transmission / reception unit 4, it is determined whether an answer back signal from the ID tag 1 has been received for a predetermined short time. Only t is determined (steps S20 and S21). If the answer back signal is not received within the time t, step S23 to be described later is performed.
If the answerback signal is received,
It is determined whether the ID code in the answer back signal matches the ID code stored in the storage device 19 in advance (step S22).

If the ID codes match, the standby loop shown in FIG. 2 (steps S2-S4)
The process returns to step S23, but if not, the process proceeds to step S23. In this step S23, it is determined whether or not the cutoff condition of the ignition circuit is satisfied only during a period until a predetermined waiting time ΔT elapses (a period until “YES” is determined in step S24). . In this case, the condition for shutting off the ignition circuit is set so as to be satisfied, for example, when any of the following conditions (1) to (4) is satisfied in a situation where the operation of the ignition switch 15 is permitted. You.

(1) When the shift position is in the parking position and the parking brake is operated with the ignition switch 15 in the ON position ON. (2) When the door is opened or opened while the ignition switch 15 is in the ON position ON and the shift position is in the parking position but the parking brake is not operated. (3) When the parking brake is operated and the door is opened or opened while the ignition switch 15 is in the ON position ON and the shift position is in the neutral position. (4) When the vehicle speed is zero and the door is opened or closed when the shift position is in the neutral position but the parking brake is not operated while the ignition switch 15 is in the ON position ON.

If the above-mentioned ignition circuit shut-off condition (both are based on the assumption that the vehicle has stopped running) is not satisfied within the waiting time ΔT, the process returns to the standby loop as it is. When the condition is satisfied (“YES” in step S23), a step S25 of outputting an alarm using a sound (for example, using a horn or a dedicated sound source) or a visual display (for example, a dedicated indicator lamp or a room light) is performed. , Until a predetermined delay time t ′ has elapsed, or until a cancel signal is input from the cancel switch 8 (step S2).
6, S27).

When the delay time t 'has elapsed without inputting the cancel signal ("YE" in step S26).
In step S "), after the engine control ECU 20 inhibits the start of the engine, the step S28 of interrupting the ignition circuit and the step S29 of resetting the permission flag F to" 0 "are sequentially executed, and then the ignition switch 15 is turned off. Is determined (step S30).

If "YES" is determined in this step S29, the process returns to the standby loop as it is, but if "NO" is determined (when the ignition switch 15 is at any position other than the OFF position OFF), the switch actuator is turned off. 18 turns the ignition switch 15 to the off position O
After executing step S31 of moving to the FF, the process returns to the standby loop. When the ignition switch 15 is moved to the OFF position OFF, the rotation operation of the ignition switch 15 is performed by the switch actuator 18.
To return to the state forbidden.

If a cancel signal is input before the delay time t 'has elapsed ("Y" in step S27)
ES ”), the control waits until the ignition switch 15 is operated to a position other than the ON position ON (except for the start position ST) (step S32), and when the operation is performed, the control from step S28 is executed. And then return to the standby loop.

As a result of the execution of steps S19 to S32 as described above, when the permission flag F is set, that is, when the ignition circuit can be formed (including the state in which the ignition circuit is formed), the vehicle side When the driver carrying the ID tag 1 storing the same ID code as described above is separated from the driver's seat by a predetermined distance or more (or the ID tag 1 is moved to an area other than the communication area with the transmitting / receiving unit 4). ), An alarm is output only when any of the above-described interrupting conditions (1) to (4) of the ignition circuit is satisfied, and when the predetermined delay time t 'has elapsed, the ignition is performed. The circuit becomes interrupted. In this case, the permission flag F is reset at the same time when the ignition circuit is cut off. When the ignition switch 15 is at any position other than the OFF position, the ignition switch 15 is automatically returned to the OFF position OFF. Will be.

Note that, in a state where the shift position is other than the parking position and the neutral position, and in a state where the vehicle is running even when the shift position is in the neutral position, that is, at least in a state where the vehicle is running, the above-mentioned state is obtained. No interruption operation of the ignition circuit is performed.

Further, if the cancel switch 8 is operated before the delay time t 'elapses after the start of outputting the alarm as described above, the above-described control for shutting off the ignition circuit is not performed ( The output of the alarm is stopped), and then the ignition switch 1
5 is operated to the accessory position ACC or the OFF position OFF for the first time, so that the ignition circuit shuts off.
Reset of permission flag F, ignition switch 15
Is returned to the off position OFF.

On the other hand, even in the case where "NO" is determined in the step S18, the step S33 of transmitting the trigger signal from the transmitting / receiving unit 4 is executed. After the execution of step S33, it is determined whether or not the answer back signal from the ID tag 1 has been received for a predetermined short time t (steps S34 and S35). If the answer back signal is not received within the time t, the process proceeds to step S37 described later. If the answer back signal is received, the ID code in the answer back signal is stored in the storage device 19 in advance. It is determined whether the ID code matches the ID code (step S36).

If the ID codes match, the process returns to the standby loop, but if they do not match, step S
Move to 37. In this step S37, it is determined whether or not the ignition switch 15 is at the accessory position ACC. If “NO” is determined here, the process returns to the standby loop, but if “YES” is determined. In step S38, in which the ignition switch 15 is moved to the OFF position OFF by the switch actuator 18, the process returns to the standby loop.

Although not specifically shown in FIGS. 2 and 3, the ignition switch 15 is turned off.
In this state, control is performed to switch a steering lock mechanism (not shown) to a locked state.

In short, according to the configuration of the present embodiment described above, when the driver carrying the ID tag 1 storing the same ID code as that of the vehicle enters the driver's seat, the operation of the ignition switch 15 is performed. The state is switched to an allowed state, that is, a state in which the engine can be started. When the driver carrying the ID tag 1 gets off from such a state (the communication area between the ID tag 1 and the transmission / reception unit). In other words, the ignition circuit is shut off and the engine is stopped only when a preset condition for shutting off the ignition circuit is satisfied.

Therefore, even if the driver carrying the ID tag 1 gets off the vehicle without performing the operation of shutting off the ignition circuit by the ignition switch 15,
Since the ignition circuit is automatically cut off and it becomes impossible to drive the automobile, the safety against theft of the automobile can be improved.

In this case, since the ignition circuit shut-off condition includes at least the stopped state of the vehicle, it is possible to reliably prevent a situation in which the ignition circuit is inadvertently shut off in the running state of the vehicle and the engine is stopped. become.

When the control for automatically shutting off the ignition circuit is performed as described above, an alarm using a sound or a visual display is output prior to the control.
The driver holding the D-tag 1 has the ignition switch 1
If the driver gets off the vehicle without operating the ignition switch 5 to the OFF position OFF, the ignition switch 15
It becomes possible to cope with the forgetting of the operation, thereby improving the convenience.

The control for shutting off the ignition circuit as described above is performed when a preset delay time t 'has elapsed, so that the automatic stop operation of the engine may be performed more frequently than necessary. It can be prevented beforehand.

In this case, after the ignition circuit is once formed, an alarm is output even if the ID code 1 breaks down and the ID code reception continued by the transmitting / receiving unit 4 is stopped halfway. If the cancel switch 8 is operated within the delay time t 'after the start,
While the ignition switch 15 is in the ON position ON, the configuration of the ignition circuit can be maintained as it is. Therefore, even if the ID tag 1 breaks down, the vehicle can be driven to the destination, which is useful in actual use. After this, the ignition switch 15
Is operated to the accessory position ACC or the off position OFF, the ignition circuit is cut off at the time of the operation to stop the engine.

The transmission / reception unit 4 is configured to intermittently transmit a valid trigger signal within a predetermined transmission area, and the ID tag 1 receives the trigger signal when receiving the trigger signal.
Since the transmission operation of the answerback signal including the D code is performed, the consumption of the power supply (usually a battery) required for the ID tag 1 can be minimized.

Since the ID tag 1 has a function of a remote controller for locking and unlocking the vehicle door through the door lock mechanism 16, the added value can be increased and the ID tag 1 can be added. Although the control of the lock mechanism 16 is also performed, the cost of the entire vehicle can be reduced.

In the case where the ignition circuit cutoff control is performed as described above, when the ignition switch 15 is at a position other than the OFF position, that is, when the driver carrying the ID tag 1 turns the ignition switch 15 off. When the user gets off the vehicle without operating to the position OFF, the ignition switch 15 is automatically moved to the OFF position OFF, so that the convenience in an actual use condition is improved, and unnecessary consumption of the vehicle battery is prevented. Can be prevented.

Further, when the driver carrying the ID tag 1 gets off with the ignition switch 15 in the accessory position ACC, that is, the transmission / reception unit 4
Even when the state of continuing to receive the ID code from the D tag 1 is stopped halfway, the ignition switch 1
Since the position 5 is automatically moved to the off position OFF, the convenience in an actual use state is improved, and wasteful consumption of the vehicle-mounted battery can be prevented.

Since the condition (3) is set as the interruption condition of the ignition circuit, when the ignition switch 15 is in the ON position ON and the shift position is in the neutral position,
The ignition circuit is not interrupted just by operating the parking brake, so when driving a car and stopping at a railroad crossing or intersection for a relatively long time, set the shift position to the neutral position and set the parking brake to the neutral position. Even if it is operated, the engine will not be stopped carelessly.

The present invention is not limited to the above-described embodiment, but can be expanded or modified as described below. In the above embodiment, when the cutoff condition of the ignition circuit is satisfied, the output of the alarm is controlled independently of whether or not a person is seated in the driver's seat.
A configuration may be adopted in which control is performed to output an alarm only when the human sensor 7 is in the detection state. According to this configuration, a state in which no person is seated in the driver's seat, that is, a state in which the alarm itself is meaningless Thus, there is no possibility that a useless alarm output operation is performed.

In the state where the ignition circuit is formed, the control device 3 locks the door lock mechanism 16 by the ID tag when the transmission / reception unit 4 continues to receive the ID code halfway. The configuration may be such that the ignition circuit is cut off on the premise that the circuit cutoff condition is satisfied. According to this configuration, the state in which the door lock mechanism 16 is locked by the lock signal from the ID tag 1 taken out of the vehicle compartment, that is, the state in which the driver gets off and the door lock mechanism 16 is locked. When this happens, the ignition circuit is reliably shut off, so that the security against theft is greatly improved.

When the ID code included in the lock signal received from the ID tag 1 is different from the ID code received through the transmission / reception unit 4 when the operation of the ignition switch 15 is permitted. Alternatively, the lock operation of the door lock mechanism 16 based on the lock signal may be canceled. According to this configuration, for example, when the driver holds two ID tags 1 having different ID codes, the driver operates the ignition switch 15 in response to receiving the ID code from one ID tag 1. When the operation is switched to a state where the operation is permitted, the lock operation of the door lock function 16 can be performed only by the lock signal from the ID tag 1, so that the ID tag 1 can be left in the vehicle compartment. The situation where the lock operation of the door lock mechanism 16 is performed can be prevented beforehand.

In this case, when the ID code included in the received lock signal switches the control device 3 to a state in which the operation of the ignition switch 15 is permitted within a predetermined time after the cancel switch 8 is operated. ID received through the transmission / reception unit 4 at
Even if the code is different, the lock operation of the door lock mechanism 16 based on the lock signal may be executed. According to this configuration, even if the driver holds two ID tags 1 having different ID codes, any one of the ID tags 1 can be used within a predetermined time after the cancel switch 8 is operated. Since the locking operation of the lock mechanism 16 can be performed, it is practically convenient.

Further, when the lock operation of the door lock mechanism 16 is performed based on the lock signal within a predetermined time after the cancel switch 8 is operated as described above, the shift position is shifted from the parking position to another position. The function of shutting off the ignition circuit when the operation is performed may be added to the control device 3. According to this configuration, when the driver holds two ID tags 1 having different ID codes, the engine is started by the ID tag 1 in a state where one of the ID tags 1 is left in the vehicle compartment. As a result, the situation in which the car is driven can be anticipated, so that the security against car theft can be improved.

The ID lock 1 and the door lock mechanism 16
Is provided with a remote control function for remotely controlling the ID tag 1. However, such a remote control function is removed from the ID tag 1,
A configuration may be adopted in which a dedicated remote controller for performing the locking and unlocking operations of the door lock mechanism 16 is provided.

Although a sensor utilizing microwaves, ultrasonic waves, light, or the like is used as the human sensor 7, a configuration in which the human sensor is realized by a seat switch or the like provided in the driver's seat may be used. However, the human sensor 7 is not always necessary. For example, if the transmission / reception unit 4 performs an operation of transmitting a trigger signal at regular intervals, the human sensor 7 becomes unnecessary. As a main switch,
Although the ignition switch 15 operated by the operation dial 15a is provided, an ignition switch operated by an engine key may be provided as a main switch.

Although the ignition switch 15 is always configured such that the rotation operation from the initial position, ie, the OFF position OFF, is prohibited, the operation itself is always invalidated (that is, the accessory position ACC, ON position). The operation to the position ON and the start position ST is possible, but the operation state may be such that an accessory circuit or an ignition circuit is not formed. In this case, when the driver holding the ID tag 1 storing the same ID code as that of the car comes close to a predetermined distance from the driver's seat, the operation of the ignition switch 15 is performed. Is validated. Although the description has been given of the embodiment in which the invention is applied to an automobile using an engine as a power source, the invention can be applied to an electric automobile, a hybrid car, and the like.

According to the present invention, as apparent from the above description, the vehicle running circuit is formed when the ID code received from the portable storage carrier matches the ID code registered in the vehicle in advance. In the case of adopting a configuration in which the operation of the main switch is performed to allow or validate the operation of the main switch, a predetermined state is set when the state of continuously receiving the ID code is stopped halfway while the vehicle driving circuit is formed. The vehicle is left in a state in which the vehicle can be driven by forgetting to return the main switch, because auxiliary control means for interrupting the vehicle traveling circuit is provided on the assumption that the circuit interruption condition of the above is satisfied. Security can be prevented beforehand, and it is possible to cope with a situation where the memory carrier is left in the passenger compartment, ensuring sufficient security against vehicle theft. It is intended to achieve the beneficial effect of kill.
